It represents approximately 5-7% of benign bone tumors and occurs in two presentations: monostotic, which is the most common, and polyostotic. The proximal femur is one of the most common locations for benign tumors, including FD. Fractures in pathological terrain are often the first symptom. In the context of a proximal femur fracture with a benign tumor, the indications for carrying out a total femoral resection are: multiple lesions in the femur or primary diaphyseal tumors, lesions that extend proximally and distally to exceed the epimetaphyseal junction area, and those that do not allow the joint to be adequately preserved. Currently, proximal or total femoral resection is considered a good therapeutic option to carry out endoprosthetic replacement using modular megaprosthetic systems. We present the case of a 27-year-old male patient, who came to the emergency department with a basicervical fracture of the right femur in Garden II Pauwells III AO 31B2.3r pathological terrain, after presenting a low-energy injury mechanism characterized by axial loading with rotational component of the right hip. This patient has a history of intralesional resection, application of bone graft and prophylactic fixation using unspecified osteosynthesis material in the pertrochanteric region 20 years ago; the biopsy would later show DF; the osteosynthesis material was subsequently removed one year later. Due to the characteristics of the fracture and as a definitive and curative therapeutic method, it was decided to carry out wide resection of the proximal femur and total hip arthroplasty with a modular prosthesis with cerclage placement, as well as taking an excisional biopsy that would later corroborate that it was the same FD treated in childhood.","PeriodicalId":101296,"journal":{"name":"Acta ortopedica mexicana","volume":"39 1","pages":"38-43"},"PeriodicalIF":0.0,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143044025","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Magnetic resonance imaging (MRI) serves as a precise alternative. The correlation and diagnostic agreement between MRI and arthroscopy are unclear in the Mexican population.Material and methods: adults with rotator cuff syndrome who underwent shoulder arthroscopy and MRI were included. Findings were classified as total tear (100%), partial tear grade I (< 50%), partial tear grade II ( 50%), or no tear. Concordance and correlation between MRI and arthroscopy were evaluated. The accuracy, sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) of MRI for diagnosing rotator cuff tears were calculated.Results: we included 147 patients with rotator cuff syndrome. MRI identified tears in 83%, of which 91.8% were confirmed by arthroscopy. Diagnostic agreement between arthroscopy and MRI was moderate (kappa = 0.452, p = 0.0001). Similarly, arthroscopy and MRI showed moderate agreement in classifying partial tears grade I, partial tears grade II, and complete tears (kappa = 0.412, p = 0.0001). Significant correlations were found in detecting partial tears grade I, partial tears grade II, and complete tears (rho = 0.77, p = 0.0001) between MRI and arthroscopy.Conclusions: magnetic Resonance Imaging (MRI) and arthroscopy demonstrated moderate diagnostic agreement (kappa = 0.452, p = 0.0001) along with a strong positive correlation (rho = 0.77, p = 0.0001) for detecting rotator cuff tears, regardless of severity.","PeriodicalId":101296,"journal":{"name":"Acta ortopedica mexicana","volume":"38 5","pages":"279-284"},"PeriodicalIF":0.0,"publicationDate":"2024-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142718061","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It occurs in 8-11% of patients aged over 40 years. Failure to detect and alleviate foraminal constriction can contribute to up to 60% of instances of unsuccessful lumbar surgery. This study aimed to develop an index to assess the extent of foraminal narrowing, thereby aiding decisions regarding direct or indirect foraminal decompression.Material and methods: a cross-sectional study was conducted, involving 49 patients, wherein measurements of all five lumbar foramina were taken using X-rays and simple magnetic resonance imaging. These measurements primarily focused on the foraminal width and the lower endplate, which were then correlated to establish a foraminal width/lower endplate index.Results: the foraminal width/lower endplate index < 10% yielded an odds ratio (OR) of 3.07 on lateral radiography, 3.59 on flexion radiography, and 4.01 on extension radiography. In MRI, an OR of 0.195 was found for the left foramina, while an OR of 3.07 was observed for the right foramina.Conclusion: this study paves the way for further exploration of preoperative and postoperative clinical outcomes across various surgical decompression methods guided by the FW/LE index. To enhance decision making, it is recommended to conduct research comparing pre- and postoperative clinical findings in individual patients, considering their FW/LE index measurements.","PeriodicalId":101296,"journal":{"name":"Acta ortopedica mexicana","volume":"38 5","pages":"285-290"},"PeriodicalIF":0.0,"publicationDate":"2024-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142718130","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Currently, the advances that have been implemented in arthroscopy allow us to repair meniscal injuries that in the past were considered irreparable. Although our priority is to preserve as much of the meniscus as possible, there are cases in which the injury reaches such complexity that this is impossible, with partial or total meniscectomy being the only therapeutic option. In the United States, approximately 690,000 partial meniscectomies are performed each year. This situation makes us consider meniscal transplantation as a great therapeutic option for patients considered young enough for joint replacement. The ideal patient is a relatively young patient (between skeletal maturity and 50 years), who has a well-documented history of partial or total meniscectomy, pain well localized to the affected compartment, with failure to conservative treatment and without high-grade chondral defects. in a generalized way. We present the case of a 35-year-old male patient with a history of total meniscectomy of the right lateral meniscus seven years ago, who currently presents with a postmeniscectomy syndrome of the lateral compartment. Due to the clinical and demographic characteristics of our patient, as well as the findings in the imaging studies, meniscal transplantation with allograft represents an excellent alternative to alleviate the symptoms and slow down as much as possible the need for joint replacement as a definitive treatment.","PeriodicalId":101296,"journal":{"name":"Acta ortopedica mexicana","volume":"38 5","pages":"351-357"},"PeriodicalIF":0.0,"publicationDate":"2024-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142718064","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Controls: experienced prosthetic replacement without fracture (n = 19).Results: pain intensity (VAS) was the most important aspect (p = 0.01), predominating in the controls. The simple radiological parameters did not show statistically significant findings predictive of peri-prosthetic fracture (number of Gruen zones, sum of them in mm, stress shielding, pedestal, polyethylene wear, stem subsidence). The role of complementary tests (CT and scintigraphy) for the definitive diagnosis of loosening was relevant, but not significant. The type of implant showed no differences. Overall implant survival was higher in cases than in controls (p = 0.016). This difference continues when comparing each loosened stem until fracture or replacement (p = 0.024).Conclusion: the main factor protecting against fracture is the replacement of a stem with clinical and radiological diagnosis of loosening. Adequate follow-up of the patient plays a determining role in this, especially when considering the greater intensity of pain in the controls, which used to guide surgeons to perform replacements before the fracture occurred. This is reinforced if we take into account that up to one third of the cases did not have regular check-ups, and therefore did not have the opportunity for replacement prior to the fracture. The role of complementary tests (CT and scintigraphy) is also very important, taking into account the low diagnostic yield obtained from simple X-rays.","PeriodicalId":101296,"journal":{"name":"Acta ortopedica mexicana","volume":"38 5","pages":"291-297"},"PeriodicalIF":0.0,"publicationDate":"2024-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142718077","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
